Question 150
A trusted employee's Wi-Fi badge suddenly produces building entries in two distant sites minutes apart, and reader identifiers share cloned UID data. Which physical attack is plausible?
Explanation
Correct Answer
Duplicate credential identity at incompatible locations suggests token copying or reader spoofing. For this case, and reader identifiers share cloned UID data. Malware and active-attack categories are distinguished by their observed payload behavior, spread mechanism, access path and outcome. The competing choice “Normal password-expiration behavior” addresses a different mechanism: computer account password changes do not clone building access tokens. That difference is material to the requested decision. Incompatible simultaneous badge sightings should trigger validation of access-reader logs and physical custody; a cloned identifier is a plausible cause, not proof of who used it.
Incorrect Answers
Computer account password changes do not clone building access tokens. Authentication checks a claimant, but it does not automatically narrow resource privileges or invalidate a different leaked secret. Here the decisive fact is and reader identifiers share cloned UID data. “RFID credential cloning or copied badge identifier” matches that requirement because duplicate credential identity at incompatible locations suggests token copying or reader spoofing.
Rollback can revert records but does not create a second active physical badge identity. Malware and active-attack categories are distinguished by their observed payload behavior, spread mechanism, access path and outcome. In the reported situation, and reader identifiers share cloned UID data. The effective mechanism is “RFID credential cloning or copied badge identifier”: duplicate credential identity at incompatible locations suggests token copying or reader spoofing.
Name resolution does not account for physical badge observations. DNS determines how names resolve to network destinations; it is not by itself a mechanism for validating a human identity or code provenance. Here the decisive fact is and reader identifiers share cloned UID data. “RFID credential cloning or copied badge identifier” matches that requirement because duplicate credential identity at incompatible locations suggests token copying or reader spoofing.
